SBA’s Proposed Overhaul of Small Business Size Standards: What US Small Businesses Need to Know

On August 20, 2026, the Small Business Administration proposed the most consequential restructuring of small business size standards in decades. If your business touches federal contracting in any way, or you have ever wondered whether you technically still qualify as “small,” this is worth understanding before the comment period closes on September 21, 2026.

What Is Actually Changing

Size standards are the thresholds the SBA uses to decide which companies count as a small business for federal contracts, loans, and other SBA-backed assistance. The proposed rule raises those thresholds significantly across professional services, information technology, engineering, and related markets, in some cases by tenfold or more. A company that has been locked out of small-business set-aside contracts because it grew past the old threshold could suddenly qualify again under the new one.

Why This Matters Even If You Do Not Do Federal Contracts

Size standards ripple outward beyond direct government work. They affect eligibility for SBA loan programs, certain tax provisions tied to small business status, and how agencies structure their solicitations in the first place. A higher threshold in your industry can also change who you are competing against, since businesses that used to be classified as “other than small” may now be bidding in the same small-business pool as you.

The Professional Services and IT Threshold Jump Is the Headline

These two sectors see some of the largest proposed increases. If you run a consulting firm, an IT services company, or an engineering practice that has stayed cautious about growth specifically to preserve small-business status, this proposal is worth reading in full rather than relying on a summary, since the exact revised thresholds vary meaningfully by NAICS code.

What to Actually Do Before September 21

Check your current NAICS code classification and compare it against the proposed new threshold for that code. If the change affects your eligibility for contracts you currently rely on, or contracts you were previously priced out of, this is the moment to submit a comment through the Federal Register, not after the rule is finalized. Public comment periods on size standard changes are exactly where affected businesses have historically shaped the final outcome.

The Bigger Picture: What Counts as “Small” Keeps Shifting

This is not the first time size standards have been adjusted, and it will not be the last. Businesses that treat their SBA size classification as a fixed fact rather than something to periodically re-check tend to be the ones caught off guard when a threshold moves, either losing eligibility they assumed was permanent or missing new opportunities they now qualify for.

None of this requires a lawyer to start understanding. It requires ten minutes finding your NAICS code and comparing it against the proposed rule, which is more time than most businesses currently affected by this change have spent on it.
